CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of U.S. Provisional Patent Application Ser. No. 63/221,799 filed Jul. 14, 2021, entitled Product Dispensing Hairbrush, the entire contents of which are incorporated by reference herein for all purposes.

FIELD OF THE INVENTION

The present invention generally relates to a hairbrush. More specifically, the present invention relates to a hairbrush configured to dispense a substance, for example, dry shampoo powder through a plurality of hollow bristles over the user's scalp during hair combing or brushing. The user may conveniently use the hairbrush for uniformly dispensing the substance over the scalp with minimal effort.

BACKGROUND

Haircare products are part of a multi-billion dollar a year business, which is consistently growing. One product that has specifically experienced growth is dry shampoo, which is a type of shampoo that reduces hair greasiness without the need for water. It may be in powder form and is typically administered from an aerosol can. In addition to cleansing hair, it can also be used as a tool for hairstyling as it can create volume, help tease hair, keep bobby pins in place, and be used in place of mousse in wet hair. Consequently, hairstylists like to use dry shampoo on their clients and consumers often use dry shampoo from their homes or on the go.

When a stylist is working on a client, their hands need to be as free as possible to style the client's hair. As such, it is not ideal to hold both a brush and a bottle of product (e.g., dry shampoo) in their hands because it leaves the stylist with no free hands to assist in the styling process. Furthermore, as salons become increasingly crowded, the space for each station lessens. It is difficult on stylists to use products if they cannot be at the station due to overcrowding of products at the station.

Moreover, both hairstylists and even more so, home users, struggle with the correct usage of shampoo and other products to use (e.g., conditioner). For instance, they are often unaware about the right amount of hair care products that are required for effective hair care. The reason is the erratic distribution of the hair care products on the hair, resulting in piling the hair care product on top and not distributing it to the ends.

While combs and hairbrushes used for grooming and styling of hair are well known dispensing hairbrushes used during the grooming and styling processes, they do not adequately address the above-described problems. The existing hairbrushes and applicators are complex in function and are not able to distribute product appropriately.

In light of the above-mentioned problems, there is a need for an improved hairbrush configured to dispense a substance, for example, dry shampoo powder.

SUMMARY OF THE INVENTION

The present invention generally discloses a hairbrush. Further, the present invention discloses a hairbrush configured to dispense a substance, for example, dry shampoo powder over the user's scalp during hair combing or brushing. The user can conveniently use the hairbrush for uniformly dispensing the substance over the scalp with minimal effort.

In one embodiment, the hairbrush is configured to store one or more substances/hair care products and/or substances, for example, dry shampoo powder.

In one embodiment, the removable cap is configured to enable the user to fill or refill the internal cavity of the handle with one or more fluids/hair care products and/or substances. In another embodiment, a friction fit, or other type of closure mechanism may be used.

In another embodiment, the hollow bristles may define a hollow cross-section, for example, a substantially circular tube-like cross-section. The length and the distribution of hollow bristles may vary widely, depending on the type of hairbrush design, the aesthetic appeal sought, or the styling effect desired.

In another embodiment, the handle is configured to rotatably connect to the head portion, thereby enabling the user to open and close the passageway for dispensing the stored substance by rotating the handle. In yet another embodiment, the handle is further configured to connect to the head portion using a slidable partition, which is mechanically connected to a slider, thereby enabling the user to open and close the passageway for dispensing the stored substance by moving the slider. In some embodiments, the switch is at least any on-off, but not limited to, a button, a slider, a pushbutton, a lever, a pin, a knob, and a touchscreen. The handle and/or the head portion are provided with the ability to truly control variable amounts of substance, for example, a dry shampoo powder using a slide or rotation handle approach based as a value proposition.

In one embodiment, the hairbrush 800 is configured to dispense a substance over the user's scalp during hair combing or brushing and is further configured to store one or more fluids/hair care products and/or substances, for example, a dry shampoo powder from an internal bulb located in the handle and squeezable by a user. In one embodiment, the hairbrush 800 is further configured to allow the user to manually control the amount of the substance which dispenses during hair-brushing due to the user squeezing the bulb with the user's fingers.

In one embodiment, the hairbrush 800 comprises a head portion 802, a plurality of bristles 814, and a handle 804 having a hollow interior 806 and two opposing apertures (808, 1204), one of which is shown in FIG. 8 and the other being show in FIG. 12 . In one embodiment, the head portion 802 comprises the bristles 814 are outwardly extended from a front face 816 of the head portion 102 of the hairbrush 800.

The front face 816 comprises an outer edge 820 at which a first nozzle 810 and second nozzle 812 is positioned. The first nozzle 810 may be positioned at the distal end and the second nozzle 812 may be positioned at the proximal end of the head 802. The nozzles, described in further detail with relation to FIG. 14 and FIG. 15 , are in internal communication with the hollow interior of the head and the bulb positioned in the handle via multiple offices described in greater detail with reference to FIG. 9 -FIG. 15 . In embodiments, the nozzles are configured to eject product in response to an action of the user, in this case, application of pressure to a bulb at the handle portion. The front face 816 may be manufactured from or coated with a hydrophilic substance so that the product doesn't run off the front face 816 and to ensure the product coats the entire front face while in use.

Referring now to FIG. 9 , a perspective view of a bulb in an embodiment of the present invention is shown generally at 900. The bulb comprises a body 902, an opened top end 904, a tube portion 906 and an open bottom end 908. While in the shape of a bulb, the bulb may be any shape and size and made of any material that exhibits hand-feel that is comfortable to the touch of a user and proper elasticity. For example, rubber may be used because its low modulus of elasticity and its capability of sustaining a deformation of as much as 1000 percent, and after such deformation, quickly and forcibly retracts to its original dimensions. Rubber is just one example, and silicone nitrile, vinyl and neoprene may be used among other materials.

The body 902 of the bulb, on its bottom end, is attached to or coupled with a tube portion 906 that in embodiments is made of a more rigid material than the bulb body 902 to allow a user to easily fill the bulb with product, whether it be potion, powder or the like. The tube portion 906 comprises an opening 908 in its bottom end in this regard. The bulb 900 is dimensioned so that it fits snuggly in the handle 804 and so that the body 902 is depressible by the user via the apertures 808 and 1204. In this way, the body portion “fills in” the apertures so that the body portion is either flush with the handle 804 or protrudes slightly from the handle 804 allowing the user to, in a single gesture with one hand, squeeze product from the brush handle into the brush head and out of the nozzles during use. In this regard, top opening 904 is opened to allows for egress of product into the brush head, and is communication with the internal portions of the tube.

With reference now to FIG. 10 shows a bottom internal perspective view of a hairbrush for dispensing a substance. The internal portion of the brush comprises a first distal cavity 1002 and a second proximal cavity 1004 separated by trammel 1006 that forms the dimensions of the each of the cavities by providing sidewalls therefor. Each of the cavities 1002 and 1004 are dimensioned to retain product introduced from the handle portion when the pressure is applied by the user, and when full, expel product from the nozzles based on additional pressure applied by the user when in use or when product is needed or desired for the client's hair. A cover is provided to cover the back of the brush head and the cavities 1002 and 1004. In operation, the internal portion of the handle and each of the cavities 1002 and 1004 are in internal communication so that product can pass therethrough. While two cavities are shown, a single cavity may be utilized herein.

The trammel 1006 may be a removable plastic piece that acts to separate the cavities, and also to pipe product from one cavity 1002 to another cavity 1004. In this way, having two cavities that are piped together, the flow rate for each of the nozzles is optimized so that product comes out of each of the nozzle roughly equally when the user depresses the handle.

With reference now to FIG. 11 , a zoomed in bottom internal perspective view of a hairbrush for dispensing a substance is shown. In this embodiment, the internal cavity 1002 is shown. The internal cavity 1002 is in fluid communication with the handle 804 via pipe 1102. The pipe 1102, in embodiments, is a hollow aperture in the handle in which the bulb is positioned so that substance or product may leave fill the cavity 1002. A nozzle feeder 1104, in embodiments, may be provided to connect an inner vertical tube to a nozzle (not shown). In this way, the product can be fed out of the inner cavity 1002 to the nozzles, the face of the brush and ultimately the user or the client's hair. However, by virtue of pressure being applied to the bulb inner tubes may not be used.

With reference now to FIG. 12 , a bottom internal perspective view of a hairbrush for dispensing a substance is shown with both cavities 1002 and 1004 are shown. As can be seen, the internal cavity 1002 is in fluid communication with the handle 804 via pipe 1102, and the cavity 1002 is in communication with the second cavity 1004 via middle piping 1202. The middle pipe 1202, in embodiments, is a hollow aperture in the trammel 1006. A second nozzle feeder (not shown), in embodiments, may be provided to connect an inner vertical tube to a nozzle shown. In this way, the product can be fed out of the inner cavity 1004 to the nozzle, the face of the brush and ultimately the user or the client's hair. However, by virtue of pressure being applied to the bulb inner tubes may not be used.

Referring now to FIG. 13 , a bottom internal perspective view and flow of product in a hairbrush for dispensing a substance in is shown. In operation, a user, whether it be a stylist working on a client or a user brushing their own hair, the user depresses the bulbs at apertures 808 and 1204 as shown by arrows 1302 and 1304, thereby pushing product up through the top of the bulb and through pipe 1102 into first cavity 1002 via arrow 1306 to fill the first cavity 1003. Product may then move through the piping 1302 out of piping 1208 and into second cavity 1004 via arrow 1308 to fill each of the cavities with product.

Referring now to FIG. 14 , a side view of a hairbrush for dispensing a substance having a nozzle is shown. The nozzle 810 that is shown in the distal nozzle (but both nozzles work similarly), and is positioned on the front face 816, and are in internal communication with the hollow interior of the head and the bulb positioned in the handle via the piping and the cavities as described earlier. In embodiments, the nozzles 812 are configured to eject product in response to an action of the user, in this case, application of pressure to a bulb at the handle portion.

The nozzle 810 comprises a hollow curved body 1404 and spout 1402. In operation, product is ejected from the spout 1402 via the hollow curved body when pressure is applied thereto. A hinged cap (not shown) may be provided to automatically close the nozzles when product is not being excreted so that during use product can remain in the cavities. However, no cap may be used and the amount of product that enters the cavities is controlled by the user based on the pressure applied to the bulb via the handle.

Referring now to FIG. 15 , a side view of a hairbrush for dispensing a substance is shown. The nozzle 812 that is shown in the proximal nozzle (but both nozzles work similarly), and is positioned on the front face 816 at the proximal end, and are in internal communication with the hollow interior of the head and the bulb positioned in the handle via the piping and the cavities as described earlier. In embodiments, the nozzles 812 are configured to eject product in response to an action of the user, in this case, application of pressure to a bulb at the handle portion similar to nozzle 810.

Referring now to FIG. 16 , an end view of a hairbrush for dispensing a substance is shown. In one embodiment, the hairbrush 800 further comprises a removable cap or an end cap 1602, which is threadably secured to a threaded portion 1604 at a bottom portion of the handle 804. In one embodiment, the removable end cap 1602 is configured to enable the user to fill or refill the internal cavity 806 of the handle 804 with one or more fluids/hair care products and/or substances. While the cap is threaded, other closing mechanisms may be employed.
